How to connect the spring inside an Ultegra Di2 9070 rear derailleur?


Cleaning our new tandem the other day, I noticed that the rear derailleur mechanism had a spring loose!

Amazingly the gears were shifting fine without it, but still, this doesn't look right?



This doesn't look right.

On closer inspection, I could see a "spare peg" (a cross head screw) in the mech, visible just behind the loose end of the spring here:


With a bit of careful pliering, I was able to hook the spring to said peg. This looks more natural when operating:


But the question I still have is, did I get that right? Answers on a postcard please! (or the comment box below will also work)
